LORAN-D Prototype Tethered Antenna Impedance and Radiation Measurements
Abstract
On 23 MArch 1977, personnel from the Rome Air Development Center (RADC) and the Electronics System Division (ESD) experimentally determined the input impedance and radiation parameters of a prototype balloon-supported, 500- ft toploaded LORAN transmitting antenna at Holloman AFB, New Mexico. The tests were conducted to verify theoretical calculations and to provide data for use in designing matching networks. The input impedance was measured at seven frequencies: 82.3, 91.2, 94.5, 95.1, 100.1, 104.5, and 112.9 kHz, using a bridge substitution method. Radiation parameters were estimated at a single frequency, 99.3 kHz. Values for the effective antenna capacitance, inductance, and total resistance, as well as for the radiation resistance and effective height, are reported and discussed.
